Our invention relates to improvements in above the valves. This passage is used for fuel inlet valves and it consists in the compermitting gas to pass above the valves when binations, constructions and arrangements the engine is idling. hereinafter described-and claimed.

A st-ruction and efficient in operative results for This type of valve is an improvement over evenly distributing gas through both arms others in that the fuel from the carburetor of the intake manifold in such a manner as is evenly difiused through "the manifold as 1 to supply all of the cylinders with anequal it is passed on through the valves.
